Aeration as the only treatment for raw water treatment
No chemicals are needed to keep the water quality high in a medium-sized city in Finland where the water intake plant was renovated and the Uponor aeration tank was installed.

The Pateniemi waterfront area in Oulu, Northern Finland played a role in the history of Finnish industrialisation. In the mid-19th century, its shipyard built large merchant vessels, and later it was the location of one of the largest sawmills of its time. Now, the waterfront is entering a new era with the completion of a residential area for 2,500 inhabitants. Uponor Barrier PLUS pipes – which are both durable and non-permeable – ensure a safe supply of potable water in this area that was in industrial use for over 100 years.
HSY (Helsinki Region Environmental Services HSY) is testing a new kind of area renovation operating model in Itäranta, Espoo, where the aim is to get the area's water supply network in order once and for all. New steps are also being taken towards more sustainable construction: the selected Uponor Blue pipes utilising renewable raw materials will reduce the carbon footprint of pipeline installations by 70% compared to traditional plastic pipes.
I de senere år er kvalitetsstyring af regnvand blevet en stadig vigtigere del af byernes regnvandsstrategier. Et pilotprojekt blev lanceret i Heinola for at rense regnvand med innovative filterbrønde udviklet af Uponor. Samtidig vil der blive indsamlet værdifulde forskningsdata om regnvandskvaliteten fra to forskellige typer områder og om de rensningsresultater, der opnås med filterbrønde.
The City of Espoo is the first in Finland to introduce the Vortex stormwater separation chamber. It can be used to efficiently separate floating and descending solids from stormwater. The aim is to reduce the maintenance costs of the retention system built from stormwater tunnels and prevent solids from ending up in waterbodies.
In recent years, stormwater quality management has become an increasingly important part of urban stormwater strategies. A pilot project was launched in Heinola to clean stormwater with innovative filter chambers developed by Uponor. At the same time, valuable research data will be collected on stormwater quality from two different types of areas and on the treatment results achieved with filter chambers.
Construction of the pipe network for cooling water at the Keljonlahti power plant began in December 2008. 3,000/3,300 mm Weholite pipes were selected for the network. The combined length of the entire intake and discharge pipe network for cooling water is 1,714 metres.
The Weholite tanks, with an inner diameter of three metres, delivered to the Riihimäki wastewater treatment in Southern Finland will ensure that the plant keeps running, even during emergencies.
In an ordinary village with less than 1,000 residents, a reservoir tank would normally be unnecessary, but Tuuri in Southern Ostrobothnia in Western Finland is not an ordinary village. The village tourist attraction draws visitors up to six million visitors annually. This needs special solution for potable water delivery.
The old concrete pipe line in Raahe came to its end. The replacing pipe line was made of Uponor's newest sewer system, Ultra Double.
A Weholite alkalization plant was installed alongside new groundwater intake facility in Kuhmo, Finland. The system is built in the factory, ready for installation.
